What it does
Software knows exactly what’s happening right before it fails. Then it crashes, and that understanding disappears. Errorcore preserves that moment, the runtime context around the failures. Instead of debugging from logs and stack traces, humans and AI get the runtime evidence behind the failure, so they can understand what happened and fix it faster. We’re turning production failures from mysteries into evidence, getting recovery time down from hours to minutes.
Capture the runtime state behind production failures. Errorcore preserves locals, async context, I/O and execution evidence so humans and AI can understand why software failed.
Local state at the throw, the request and trace context, and the ordered database, cache, queue, and HTTP work that preceded it. Sensitive fields scrubbed, payload encrypted inside your process. Evaluate with non-sensitive test data. Behavior may change during beta, so keep your existing incident-response and business-continuity records. Logs and traces record that a request failed and roughly where it went. They rarely keep the values the failing frame was holding, or the exact order of work that produced them. Errorcore is the layer underneath: it captures selected execution-specific evidence at the throw and keeps it with the incident, so an investigation starts from what actually ran.…from errorcore.dev

I built a tool to get instant test results2022 · github.com · ▲96I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…
Fatal Core Dump – A debugging murder mystery played with GDBMar 2026 · robopenguins.com · ▲68Debugging a crash can sometimes feel like a noir detective story: following faint clues, chasing red herrings, and eventually hitting the moment where the whole case finally makes sense. I leaned into that idea and built Fatal Core Dump, a small game where the investigation is real crash debugging. The game gives you a Linux binary, its core dump, a source file, and some logs. You solve the mystery by debugging it. The premise: an engineer dies when an airlock on an asteroid mining station opens unexpectedly. Your job is to determine whether it was a simple software bug or something more…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
